ABSTRACT:
In the manufacture of a gated can lid preparatory to attaching the lid to the body of a can, a pushdown gate is first formed in a metal blank prior to cutting the outline of the lid. The gate is cut in a panel which is integral with the lid, below an aperture in the lid, and beneath an underfolded, interconnecting spacer strip about this aperture. After the lid outline is cut from the blank, the circumferential chuck panel, seaming panel and curl are formed to complete the gated lid.
